Asthma sufferers have been urged to check for faulty inhalers which could be putting thousands of lives at risk.

Two brands of inhalers have been recalled over fears they not be correctly delivering potentially life-saving medication.

More than 5.4million people in the UK affected by the condition are being warned to to check if they have specific batches of Ventolin Accuhaler inhalers, which are used for the emergency relief of asthmatic symptoms.

Experts warned that due to a manufacturing issue a small number of the devices are not delivering the full number of doses.

One lot of Seretide Accuhaler, used for the maintenance of preventative treatment of asthma, is also being recalled from hospitals, pharmacies, dispensing practices, retailers and wholesalers in the UK.

The recall of Seretide Accuhaler is only at pharmacy level because this is used for maintenance treatment as opposed to a reliever treatment.

More than 4,500 Ventolin 200mcg inhalers and 1,400 Seretide 50/250mcg inhalers are affected, a spokesman told The Sun Online.

Three people die from an asthma attack every day in the UK - but charity Asthma UK say two thirds of these deaths can be prevented if people get the correct treatment.

MHRA say patients who have used the affected batches of Ventolin may find that their symptoms are not relieved as normal by their Ventolin Accuhaler.

If this happens, they should seek medical advice and return any affected Accuhalers to their pharmacist for a replacement.

Only a small proportion of the two affected batches of Ventolin Accuhaler and the one affected batch of Seretide distributed to the UK market are defective.

Bernadette Sinclair Jenkins, MHRA’s Regulatory Assessment Unit Manager of the Inspections, Enforcement and Standards unit said: "It is important people check whether they have an affected inhaler.
